U.S. Invasive Species Impact Rank (I-Rank)
Help
Disclaimer: While I-Rank information is available over NatureServe Explorer, NatureServe is not actively developing or maintaining these data. Species with I-RANKs do not represent a random sample of species exotic in the United States; available assessments may be biased toward those species with higher-than-average impact.

I-Rank: High/Low
Rounded I-Rank: Unknown
I-Rank Reasons Summary: Nicotiana glauca can be locally abundant and cause reductions in native plant community richness; however, these effects do not appear to be widespread over the entire range in the U.S.
Subrank I - Ecological Impact: Medium/Low
Subrank II - Current Distribution/Abundance: High/Medium
Subrank III - Trend in Distribution/Abundance: High/Low
Subrank IV - Management Difficulty: High/Low
I-Rank Review Date: 02Apr2004
Evaluator: Fellows, M.
Native anywhere in the U.S?
Native Range: South America and Tropical, Central America (Weber 2003).

Screening Questions

S-1. Established outside cultivation as a non-native? YES
Comments: (Weber 2003).

S-2. Present in conservation areas or other native species habitat? Yes
Comments: Inhabits riverbanks, desert scrub, arid grassland, coastal beaches and rocky places (Weber 2003). Along streams, ditches and washes (Kearney and Peebles 1951).

Subrank I - Ecological Impact: Medium/Low

1. Impact on Ecosystem Processes and System-wide Parameters:Low significance
Comments: Nicotiana glauca has a high transpiration rate, which may cause water supply problems for other plants (Brandes 2002).

2. Impact on Ecological Community Structure:Moderate significance
Comments: Shrub or small tree, 2-8 m in height (Weber 2003). Forms dense stands (Weber 2003). Shades out understory (Weber 2003).

3. Impact on Ecological Community Composition:Moderate significance
Comments: Forms monotypic stands (Weber 2003). Prevents native species regeneration (Weber 2003).

4. Impact on Individual Native Plant or Animal Species:Unknown

5. Conservation Significance of the Communities and Native Species Threatened:Medium/Low significance
Comments: Riverbanks, desert scrub, arid grassland, coastal beaches and rocky places (Weber 2003). Along streams, ditches and washes (Kearney and Peebles 1951).

Subrank II. Current Distribution and Abundance: High/Medium

6. Current Range Size in Nation:High significance
Comments: Many states in southwest US, CA to TX, also including HI, GA, AL, FL, OH and NJ (Kartesz 1999).

7. Proportion of Current Range Where the Species is Negatively Impacting Biodiversity:Medium/Low significance
Comments: Inferred - negative effects seem to be associated with presence in the southwest, no negative reports from east or southeast.

8. Proportion of Nation's Biogeographic Units Invaded:Moderate significance
Comments: Potentially in 35 ecoregions (inferred from TNC 2001 and Kartesz 1999). However, it is likely absent from at least 5 CA ecoregions (Baldwin et al. 2004) and at least 2 FL ecoregions (Wunderlin and Hansen 2004), bringing the suspected number of ecoregions to 28.

9. Diversity of Habitats or Ecological Systems Invaded in Nation:Medium/Low significance
Comments: Riverbanks, desert scrub, arid grassland, coastal beaches and rocky places (Weber 2003). Along streams, ditches and washes (Kearney and Peebles 1951).

Subrank III. Trend in Distribution and Abundance: High/Low

10. Current Trend in Total Range within Nation:Unknown

11. Proportion of Potential Range Currently Occupied:Unknown

12. Long-distance Dispersal Potential within Nation:High/Moderate significance
Comments: Water transport (Brandes 2002). Available for sale on the Internet (02/April/04).

13. Local Range Expansion or Change in Abundance:High/Low significance
Comments: In Europe, Nicotiana glauca can spread quickly (Brandes 2002).

14. Inherent Ability to Invade Conservation Areas and Other Native Species Habitats:Medium/Low significance
Comments: Usually follows disturbances, such as fields and roads, then can spread into other plant communities from there (Brandes 2002).

15. Similar Habitats Invaded Elsewhere:High/Low significance
Comments: Europe, Africa, Australia, Asia, North America and major islands (Weber 2003). This species is considered to be a "dangerous (causing ecological damage or alteration) for natural ecosystems" in Spain (Dana et al. 2002).

16. Reproductive Characteristics:Moderate significance
Comments: Plants can flower within the first year, producing from 10,000- 1,000,000 seeds (Brandes 2002).

Subrank IV. General Management Difficulty: High/Low

17. General Management Difficulty:Moderate significance
Comments: General reccommendation, pull or dig out small plants, cut and treat stumps with herbicides for large plants (Weber 2003).

18. Minimum Time Commitment:Unknown

19. Impacts of Management on Native Species:Unknown

20. Accessibility of Invaded Areas:High significance
Comments: Blackburn's Sphinx Moth, Manduca blackburni, a federally endangered, Hawaiian insect, may depend on Nicotiana glauca for larval development, especially in the absence of native Solanaceae (USFWS 2003).
